In this video, Naomi and Rick explain how to find the equation of a line when given two points. They use the slope formula and point-slope form to derive the equation, making sure to simplify fractions along the way. The final equation is in slope-intercept form, which is ideal for practical use.
This video is on finding the equation of a line given 2 points. Both the slope formula and point-slope form are used in the process. Also, there are fractions in this one. :)
